ZXSL-601 Multifunctional Vector Analyzer: A Technical Overview
Introduction
The ZXSL-601 Multifunctional Vector Analyzer, developed by GDZX, is an advanced instrument designed for comprehensive field testing in power systems. It integrates the functionalities of a phase meter, electrical parameter tester, and harmonic analyzer, making it a versatile tool for technicians working on protection relay testing, energy metering verification, and power quality analysis.
Key Features and Advantages
Multi-Channel Vector Display
The instrument simultaneously measures three voltage and six current channels, displaying vector relationships on a single screen. This capability is particularly valuable for testing differential protection schemes (e.g., transformer or busbar differential), where traditional methods often require multiple connections and manual plotting. The ZXSL-601 reduces testing time by generating hexagonal diagrams in a single wiring setup. For constrained spaces, it supports a double-clamp method for incremental measurements.Non-Invasive Current Measurement
Using clamp-on current transformers, the ZXSL-601 allows safe and convenient current measurement without breaking current circuits, enhancing operational safety and efficiency.Protection Relay Wiring Analysis
It analyzes complex protection device wiring, identifies errors, and provides correct wiring diagrams for comparison. This feature ensures relay systems operate as designed, reducing commissioning and troubleshooting time.Electrical Parameter Measurement
The device measures three-phase voltage, current, active power, apparent power, and phase angles. It also converts values to primary-side equivalents, simplifying data interpretation for technicians.Energy Metering Verification
It detects wiring errors in three-phase three-wire metering systems, identifying all 48 possible wiring configurations. This helps prevent revenue loss due to incorrect or tampered metering.Harmonic Analysis
The analyzer performs on-site harmonic analysis up to the 32nd order and calculates total harmonic distortion (THD), aiding in power quality assessments.User-Friendly Design
A high-brightness color LCD with English menus and tactile silicone keys ensures ease of use. The wide-temperature display adapts to harsh environments, while a large lithium battery supports up to 6 hours of continuous operation.Data Management
With storage for over 2,000 records and USB connectivity, test data can be saved, uploaded to computers, and analyzed comprehensively.

Comparison with Conventional Tools
Traditional testing often requires multiple instruments (e.g., phase meters, harmonic analyzers, and electrical testers), leading to longer setup times, inconsistent data, and increased error risks. The ZXSL-601 consolidates these functions into one device, improving accuracy and efficiency. For example, differential protection testing typically involves repeated connections and manual vector plotting; the ZXSL-601 automates this process, reducing human error and saving time.
Conclusion
The ZXSL-601 Multifunctional Vector Analyzer is a robust, all-in-one solution for field technicians. Its integration of vector analysis, electrical parameter testing, and harmonic measurement—coupled with user-friendly features and portability—makes it a superior choice for modern power system testing. By enhancing accuracy and efficiency, it addresses the evolving needs of protection, metering, and power quality applications.
